5) oily but by soil medium microbial decompose and do not have noxiousness, won't gather for a long time in the environment so and cause pollution.

6) oil can be used through handling recycle, fat price is 25 yuan about / Kg, it is 5 times of transformer oil commonner.

7) content of complete flaming generation is β oil CO2 and H2O, content of incomplete combustion generation is content of the generation below action of CO2, H2­O and CO, electric arc to be C2H2. Oily photograph compares β oil and common transformer, its viscosity is apparent prep above is common transformer is oily (3cSt) . Be in when temperature - when 10 ℃ , β oil becomes very ropy, barely flows. β oily transformer agrees with the place with fire prevention and environmental protection high demand, use environment temperature should be in - 10 ℃ above, in order to assure winding, core medicinal powder heat energy force.
